HINGE.

Specification of Letters Patent.

Patented Jan. 9, 1912.

Application filed December 1, 1910. Serial No. 595,140.

To all whom it may concern:

Be it known that I, PHILIP M. BUSH, a citizen of the United States, anda resident of Hartford, in the county of Hartford and State ofConnecticut, have invented a new Improvement in Hinges, of which thefollowing is a specification.

My invention relates to the class of artlcles above named, and theobject of the invention is to provide a device of this kind having novelfeatures of advantage and utility.

A form of device in the use of which the objects herein set out amongothers may be attained is illustrated in the accompanying drawings, inwhich'- Figure 1 is a perspective view of a portion of a hood for theengine of an automobile showing my improved hinge applied thereto. Fig.2 is a detail view showing a portion of the edges of a plate constructedto form my improved hinge. Fig. 3 is a detail view in cross-sectionthrough the hinge.

While my device is not limited to any special form of a hinge it ispeculiarly adapted for use on structures where the members of the hingeare integrally formed at the edge of a sheet of metal, such a structurebeing embodied in the hood for the engine of an automobile, and for thisreason I have selected such a structure for the purpose of illustrationand description of my invention herein.

In the drawings the numeral 5 denotes one side of the top of a hood and6 the opposite side thereof, these two sides being joined at the centerof the hood by a hinge of my improved construction.

The numeral 7 denotes one of the side parts of the hood joined to theupper part 6 as by a hinge 8 as shown herein.

In constructing the hinge the plates 56 are first formed with openings89, as shown in Fig. 2, these openings providing bars 10 extending thefull length ofthe structure. The edge of each plate 5 and 6 is formed ina manner similar to the other, and a description of the format-ion ofone will therefore be understood as applying equally to the formation ofthe other. The plate 5 is curved to form knuckles 11, these knucklesbeing composed of the cross-pieces 12 between the openings 8. The bar 10beyond the knuckle is extended on to the flat portion of the plate. Theplate is bent as at .13, having a part 14 extending backwardly uponitself, and it is bent again as at 15, the main body of the plate lyingabove the part 14 as plainly shown in Fig. 1, in this figure the plate 5showing the bend or crimp in a preliminary step, and before it isfinally set to place, the plate 6 showing the hinge as completed. Thebar or edge 10 of the plate lies between the folds 14 and 16 of theplate and the bent edge 15 is forced securely into the angle between thebar 10 and the curved part of the knuckle, and is thus held by theknuckle securely against displacement. The edge or bar 10 is thussecurely held in place, and a hinge is thus formed of extreme strengthand without rivets orlike members to hold the parts in place. Theknuckles 17 on the plate 6 are formed in a similar manner, the openings,however, be ing staggered with respect to the openings on the plate 5,as shown in Fig. 2 to allow the necessary meshing of the knuckles on onepart into the space between the knuckles on the opposite part.

I have shown herein the preferred form of construction and embodiment ofmy invention, but this may be departed from to a greater or lesserextent and yet be within the spirit and intent of the invention.

I claim- 1. A hinge leaf having a knuckle formed by a turned overportion of the edge resting upon the main part thereof, and a bend in.

the main part of the leaf holding said edge in place.

2. A hinge leaf having a knuckle formed by a turned over portion of theedge resting upon the main part of the leaf, and a bend in the main partof the leaf overlying said edge to hold it in place, said bend beingforced into the angle between the knuckle and edge to retain said bendin position. v

3. A hinge leaf having a knuckle formed by a turned over edge restingupon the main part of the leaf, a" bend including one part extendingtoward the knuckle and another portion extending away from the knuckle,said bend being closed upon said edge to hold it in place.

4. A hinge leaf having a knuckle formed place, and the bend pressed intothe an le by a turned over portion of the edge resting Underneath therounded part of the knuc 1e upon the main part of the leaf, a bend inthe to hold said bent portion in place.

main part of the plate including a portion PHILIP M. BUSH. extendingtoward the knuckle and another Witnesses:

partextending away from the knuckle, said ARTHUR B. JENKINS,

parts being closed down to hold said edge in LENA E. BERKOVITCH.
